[xsl] xml to xml transform

["Anujith Amaratunga" <aamaratu@xxxxxxxxxxxxx>]

Hi,

sorry I have miss-typed the xml, so if I have the follwing xml :

<root>
 <a>
   <b>1</b>
   <c>2</c>
   <d>
      <d1>text1</d1>
      <d2>text2</d2>
   </d>
 </a>
 <a>
   <b>1</b>
   <c>2</c>
   <d>
      <d1>more text1</d1>
      <d2>more text1</d2>
   </d>
 </a>
</root>


how do I produce

<a>
  <b>1</b>
  <c>2</c>
  <d>
     <d1>text1</d1>
     <d2>text2</d2>
  </d>
  <d>
     <d1>more text1</d1>
     <d2>more text1</d2>
  </d>
</a>

I am not sure what this is called. is it grouping ?

thanks in advance.

Anu.
